Hi ELF,

This afternoon i'm attempting to transmit on my INV-L on 136.172 Hz (not 
kHz!). Just preparing my H bridge VLF PA and i intend to use an old 10 
kV transformer which i got from an old furnance (to inflame the oil 
stream), see 
https://dl.dropboxusercontent.com/u/19882028/VLF/10kV%20Trafo.jpg

Will that work on 2.4 km distance? It's well inside the near field. 
Which mode could be possible? QRSS-3? CW?
The 2200000 m band, or 2.2 Mm band :-) A near field of 350 km !!
I hope i can apply 10 kV to the antenna. It will not be resonated. And 
maybe i will see harmonics as well, because the input is rectangular...
